Description
Technical field
The present invention relates to containing the organic thickening of attapulgite clay and mechanical thickening method, being related specifically to a kind of for passing through the method for adding foodstuff glue and improving pulping process raising attapulgite clay colloid viscosity.
Background technology
In attapulgite clay colloid, the bar-shaped attapulgite crystal of fiber mutually supports and forms reticulated structure thus form colloid, and the crosslinking degree higher colloid viscosity of attapulgite crystal is larger.Industry member wishes that the viscosity of Clay Colloids is the bigger the better, and Normal practice adds MgO in attapulgite clay
2or Mg (OH)
2, and roll with roller pressure machine, but its Efficient Adhesive Promotion is limited.Organically-modified method significantly can change the surface property of attapulgite, but the research that the interpolation of organic tackifier affects colloidal property is also less.Harryman etc. (1965) find that the water solubility copolymer adding maleic anhydride and ethene can make the mud yield of palygorskite clay improve 1.5 ~ 2 times, and Sawyer etc. (1965) propose the method by adding MgO and guar gum raising palygorskite clay mud yield; But they do not solve the problem of colloid flocculation, do not inquire into pulping process yet.We by adding natural high molecular substance in attapulgite clay, and attapulgite particle and polymer are connected to form the stronger reticulated structure of crosslinking degree, thus improve the viscosity of colloid.Attapulgite has salt resistance, and attapulgite colloid to commonly use environment be saturated common salt water condition.Major part polymer indissoluble or be insoluble to saturated aqueous common salt.This patent have found the polymer dissolving in saturated aqueous common salt, and after adding, colloid viscosity is significantly improved.But in existing pulping process, the attapulgite clay colloid that with the addition of foodstuff glue is easy to form aggregate thus reduces colloid viscosity, and for this problem, we improve pulping process, restrained effectively the generation of colloidal agglomerates thing and decrease mixing time.
Summary of the invention
1, the technical problem that will solve is invented
Select and colloidal agglomerates problem for attapulgite clay organic tackifier, the invention provides a kind of for passing through the method for adding foodstuff glue and improving pulping process raising attapulgite clay colloid viscosity, by adding the foodstuff glues such as guar gum (guar gum), xanthan gum in the powder attapulgite clay of drying, add the crosslinking degree between Attapulgite stone granulate in colloid; Use the whipping device glue that shearing action is stronger, aggregate in the colloid of formation can be made to reduce, and screen over-size reduces, and improves the viscosity of colloid.
2, technical scheme
Inventive principle
Chain is rich in the foodstuff glue of polysaccharide, and as guar gum, xanthan gum etc., the colloid formed has the characteristic keeping stable (anti-salt) under strong electrolyte environment.The hydrogen bond that polysaccharide in foodstuff glue and attapulgite surface hydroxyl produce can make foodstuff glue be adsorbed on the surface of attapulgite crystal.In colloid, the polysaccharide polymer that desirable foodstuff glue is connected by bridge like forms framework, is wherein studded with attapulgite crystal, such a structure increases the crosslinking degree of attapulgite and polysaccharide, improves colloid viscosity; Not homodisperse foodstuff glue aggregate can be broken up by the pulping equipment of high shear force, thus makes the foodstuff glue powder in system maximize plastic, thus reduces screen over-size raising colloid viscosity; The polymer (brilliant bundle) of fibrous attapulgite crystal is opened into numerous monocrystalline by the pulping equipment that shearing force is stronger, thus increases colloid viscosity; The stronger pulping equipment of shearing force also can be broken thus reduce screen over-size by clay impurity.
Technical scheme of the present invention is as follows:
A kind of for passing through the method for adding foodstuff glue and improving pulping process raising attapulgite clay colloid viscosity, by adding the powder of foodstuff glue and fully mix in attapulgite clay, add saturated aqueous common salt slurrying, use high shear force pulping equipment, abundant stirring makes the two dispersed plastic, obtains full-bodied attapulgite clay colloid thus.
Described foodstuff glue is polysaccharide food glue, and described polysaccharide food glue is guar gum, xanthan gum or fenugreek gum;
The foodstuff glue powder that mass percent is 0.1% ~ 5% is added in described attapulgite clay;
The attapulgite clay g of described interpolation foodstuff glue: saturated aqueous common salt ml is 1 ~ 2g:20ml.
Described high shear force pulping equipment comprises colloidal mill, high speed hollander, average pump, clarifixator etc.
The beating time of described high shear force pulping equipment depending on the kind of foodstuff glue addition and foodstuff glue, generally between 1 ~ 3 minute.
Described high speed hollander is the blade type stirring pulping machine that rotating speed is greater than 2000 revs/min.
Described attapulgite clay is 18-200 object attapulgite clay.
3. beneficial effect
Innovative point of the present invention and feature are:
(1) foodstuff glue of the increase colloid viscosity that the present invention is used is while raising attapulgite clay colloid viscosity, have salt resistance, colloid can keep stable under ocean and high salinity environment, and tackifier are cheap and easy to get simultaneously, harmless, environmentally friendly.
(2) use the stirrer slurrying of high shear force, under equal conditions can obtain the higher Clay Colloids of viscosity.
